Class 1.2G devices are defined as which of the following?

• A. Mass Explosion; Flash Powder, Salutes in bulk.
• B. Projection but Non Mass Explosion; Fireworks (Rarely Used)
• C. Mass Fire, Minor Blast or Fragment 'most Display Fireworks'
• D. Very Insensitive Explosive

Answer: (B)

1.2G devices are items with a projection hazard but without a mass explosion. That means they can shoot or propel components and may create some fragmentation or a localized blast, but they do not unleash a large, simultaneous explosion that affects the entire device. This category is uncommon in everyday display fireworks because most display devices fall into other classes that involve more noticeable blast or fragmentation. The idea is that the main danger comes from projecting parts or flames rather than a massive blast.

In contrast, devices described as having a mass explosion hazard involve a large, widespread blast; those do not fit the 1.2G category. Devices with a mass fire or minor blast/fragment effect correspond to other classifications, and very insensitive explosives describe a different, much less reactive group altogether.
